"My Dog Mattis" is Mark Tappan's first book about his celebrity K9 dog
Mattis. Mark and Mattis have been a team for over 5 years. Mark is a 15
year veteran with the police force and Mattis is the most highly
decorated dog in the department’s history. Mark has always seen dogs as a
great bridge to connect law enforcement and the people they serve. They
have grown their following on social media to millions. They are
focused on using their platform to bring people together with fun and
creative posts while giving insight into the special bond between a
handler and K9. They appeared on the inaugural season of America’s Top
Dog on A&E winning episode four and coming in a narrow second in the
Champions Episode. That led to appearances on Entertainment Tonight,
Good Morning America, Fox and Friends and in studio hosts on LivePD.
